SPECIFICATION forming part of Letters resentido-470,425', dated march s, Isea. Application una une. 24, 1an. sel-1n no. 386,244. (no man.)

,York, have invented certain new and useful Improvements in Ozone-Machines, of which the following is a description.

The invention relates to. an apparatus for vgenerating ozone, and is especially adapted for use in theaters and similary -places for ozouizing the air.

. The invention consists in a novel arrange' ment of apparatus, and in certain combinations hereinafter set forth and claimed.

In the accompanying drawings, which`illus'v trate the improvement, Figure 1 is a front view of the case in which the apparatus is mounted, the front door being removed. Fig. 2 is a face view. of ai commutator of special construction used in the apparatus. Fig. 3 is a diagram illustrating the circuits.

Lis the ease or box, in which is a motor 2, having an armature 3 and commutator of any suitable construction. Both ends of the armature-shaft are extended. AOne end carries a commutator or circuitinterrupter 5 of special form. A face view of this device is' shown in Fig. 2.

6 is a disk on which are mounted fourl connected by the radial arms9.

10 are brushes adapted to bear on the contact-plates. It will be evident that when 7 7' are in the position Vshown the two brushes are connected. The brushes would also be con-A nected when plates 8 8' occupy the position 'of 7 7.y Between the plates 7 8 are insulated segments 11. There are preferably two or more of thesel plates in each of the Interven-` ing spaces. With this arrangement there is less danger of a gradual making and. breaking of the circuit, such as mightotherwlse hap pen owing to the formation of a conducting iilm between the plates'7 8 and the plates 11.

- At the opposite end of the armature is 'a geur or .friction wheel 12, meshing with. the wheel 13, which drives the fanof a blower 14.. From said hlowera pipe 15 extends toa chamber16, containing drying material. From the upper endy of this chamber branch pipes 17 extend to the ozone-tubes 18, which may be of any suitable construction-such, for example, .as the well -known Siemensozonetubes. Above the motor is a partition or shelf on which rest the necessary number of induction-coils 19.

2O is a switch pivoted to the inner side of the case, having a handle extending to the outside through a curved slot. f

The circuits shown in Fig. 3 are as follows:

A suitable source of current is connected to the two terminals 21 22. 21 is Iconnected to switch 20, which switch is adapted to bear on two contact-points. One point is connected by wire 24 to the commutator 4of themotor, the opposite brush of. the commutator beingconnected by wire 25 to the terminals 22.

aries of the induction-coils are united and are connected to the two terminals ofthe ozonef tubes in the well-known manner.

27 is a tube having a .bend and connected to the Omnetubes. Within the bend is placed a quantity of an'essential or volatile oil or similar material. The ozone generated passes through the oil and escapes into the air. The

quantity of4 oil in the tube' should be small,

so that there is only a short contact between the ozone and the oil. This treatment tends to 'remove the pungent odor ot the ozone, but

does not impair its usefulproperties.

' The operation of the apparatus is as follows:. The switch being moved to close the circuits described,` the motor begins to revulva-thereby driving the blower and forcing `air through the drying-chamber toA the Having thus described the invention, what .1., In an ozone-machine, the combination of tubes or receptacles in which ozone may be generated, a secondaryvcircuit of an induction-coil extending to said receptacle, a primary circuit for the induction-coil, a commu-` mary circuit for the induction-coil, a commutator or circuit-breaker for said primary circuit, an electric motor for moving it, and a x5 blower, also operated by said motor, for forcing air to thereceptacle, substantially as described.

3. In an ozone-1nachine,the combination of tubes or receptacles in which ozone .may be vzo generated, a-'seeoudary circuit of an induc-- tion-coil extending to said receptacle, a priax'y-circuit for the in d nct'ionicoil, a commutator or circuit-breaker for said primary circuit, an lelectric motor for moving it, a' dry-l z 5 ingfchamber communicating with the receptac'le, and a blower for forcing air th rough the drier to vthe receptacle, substantially as described.

4.- .In an ozone machine, the combination of 3o receptacles in which ozone may be generated for ozonizin g ai r, an ind uctioncoil, the second.-

ary of which has terminals in said receptacle and the primary of which is connnected with a suitable source of current, and a receptacle containing an essential oil or similar materiall 35 through which the ozone generated is passed, the'quantity of oil through which the ozone is passed being insu'icient to destroy the ozone, substantially as described.

5. Thecombination, in an ozone-machine, of indnotion-coilsforproducing high-tensioncurrents, an interruptor for the primary circuit of said induction-coils, andeJ motor for moving said interrupter, the motor and primary ycircuit being in multiple arc from the main- 45 su pply circuit, substantially asdescribed.

6. i The combination, in an ozone-machine, ot an induction-coil having primary and secondary circuits, an interrupter for the primary circuit consisting of plates or blocks connected in pairs, and one or more insulated plates in the spaces between said connected plates, substantially as described.

This specification signed and witnessed this 26th .day of January, 1891.
